News Summary: Lawyer says no charges for Sokol

INVESTIGATION COMPLETE: The lawyer for former Berkshire Hathaway executive David Sokol has told The Wall Street Journal and The New York Times that Sokol won't face charges from the Securities and Exchange Commission. Sokol always denied any wrongdoing.

TROUBLESOME TRADES: Sokol's trouble began when he bought nearly 100,000 shares of Lubrizol in 2011 when he knew Berkshire was in talks to buy the specialty chemical maker.

SUCCESSOR SPECULATION: Before Sokol resigned from Berkshire in 2011, many investors considered him a leading candidate to eventually replace Warren Buffett as CEO. But afterward, Buffett said Sokol's departure didn't affect Berkshire's succession plan.
